Robotic Device Tester

A device testing method, comprising:

• operating a first device according to stored test sequences;
• capturing still images of a display screen of the first device using a first camera having a field of view substantially occupied by the display screen;
• capturing video images using a second camera having a field of view in which are located the first device and a second device communicating with the first device during the device testing method;
• comparing, in a first comparison step, the captured still images with stored screenshots;
• determining whether an error has occurred based on the comparison;
• and
• conditional upon a determination that an error has occurred, storing in a memory a video clip captured by the second camera and which corresponds to a time period during which the determined error occurred.

A hardware-implemented computer-readable medium having stored thereon instructions, which, when executed, cause a processor to perform a device testing method, the method comprising:

• operating a first device according to stored test sequences;
• operating a first camera to capture still images of a display screen of the first device, the first camera having a field of view substantially occupied by the display screen;
• operating a second camera to capture video images, the second camera having a field of view in which are located the first device and a second device communicating with the first device during the device testing method;
• comparing, in a first comparison step, the captured still images with stored screenshots;
• determining whether an error has occurred based on the comparison;
• and
• conditional upon a determination that an error has occurred, storing in at least one of a memory and a disk a video clip captured by the second camera and which corresponds to a time period during which the determined error occurred.
